Even when men do more housework and child care, a lot of times it's still women in charge, delegating, so you have all that noise in your brain. You're on a bike ride or picnic with your family, and it looks like leisure, but on the inside you are keeping track of everybody's emotional temperature, and did I pack this, what are the directions, how much time are we going to be here, do we have anything for dinner? It's like a toilet running all the time.
